I swear if you lurk on the internets for long enough you can trip across some really interesting stuff — even information about the most prized of all current Sony Ericsson projects, the XPERIA X10. While the device isn’t scheduled until quarter one of 2010 for a release, we are able to narrow it down to which carrier will be seeing the device.

Of course, we’ve already heard numerous reports of the pre-order starting at a nice $1,000. Read.
